JOHN B. BOLINGER, OF JACKSON, MICHIGAN, ASSIGNOR TO HOWARD ROSS, OF SAME PLACE.

DEVICE FOR OPERATING CHURNS.

SPECIFICATION forming part of Letters Patent No. 223,700, dated January 20, 1880. Application filed December 5,1819.

To all whom it may concern:

Be it known that I, JOHN B. BOLINGEB, of Jackson, in the county of Jackson and State of Michigan, have invented an Improvement in Devices for Operating Ghurns; and I do hereby declare thatthe following is a full, clear,

and exact description thereof, reference being had to the accompanying drawings, and letters of reference marked thereon, forming a part of this specification, in which drawings- Figure 1 is afront elevation of my improved churn. Fig. 2 is a central longitudinal section of the same. Fig. 3 is a plan view with that portion of the mechanism removed which is above the line a: w of Fig. 2. Fig. 4 is a detail view, in perspective, of the pitman-connection between the dash er and the driving cam-wheel of the churn.

Like letters indicate the same parts in the several figures.

One object of my invention is to provide a churn with the means whereby a rapid reciprocating movement can be imparted to the dasher positively, which at the same time sh all only require a slight exertion of the power of I the operator.

Another object of my invention is to provide the means whereby an ordinary churndasher may be operated with ease and without binding upon the cover of the churn, although the hole in the cover through which the handle of the dasher passe-s shall not be in exact line with the longitudinal axis of the churn and a further object is to provide the means whereby the dashers of churns may be operated in the bodies of churns having different diameters.

The nature of the invention will fully appear from the subjoined description when considered with reference to the accompanying drawings, forming a part of this specification.

A in the drawings indicates the body of the churn; B, the dasher, provided with an ordinary handle, b and O, a standard for supporting the mechanism to impart motion to the dasher.

The standard 0 at its lower end is provided .with a hinged metallic clasp, c, which is conat c c, and through its perforated terminating ends a is provided with a tightening bolt and nut, as shown.

The bolt (1 is made with a grooved head, and at its opposite end is screw-threaded to receive the nut (1. suitable manner with an interior elastic lining, n, in order that a churn may be properly embraced by the clasp, although the churn-body may not be perfectly cylindric. The clasp 0,- thus constructed and held in place, as shown,

The clasp c is also provided in any is adapted for use upon churns of varying diameter, while at the sametime, by simply loosening the nut d,"the dasher being disconnected from its operating mechanism, it can readily be removed from the body of a churn, together with the superincumbent mechanism for imparting motion to the dasher.

The standard 0 has an upper bent end, as at 6, provided with screw threaded perforations to receive a screw-bolt, e, by means of which an adjustable standard, D, is held in position upon the standard 0.

V The standard D is slotted longi at f, a greater portion of its length to receive a metallic pitman connection, by which the dasher B is connected with a driving camwheel, F, applied to the upper end of the standard by means of a screw-bolt, 6 as shown. The lower supporting end of the standard D is also slotted, as at f, thereby permittingthe standard, with its pitman -connection E and cam-wheel F, to be adjusted bodily nearer to or farther from the longitudinal axis of the bodyof a churn, according to the diameter of such body. a

The cam-wheel F is made of cast metal, and

tudinally, as.

with its perimeter 9 weighted, as indicated in i the drawings, in order that it may act also as a balance-wheel. It is constructed with a central portion, G, of the form represented in Fig.

pitman-connect-ion E, travels during the operation of the churn.

The inner or edge faces, as at i, of the inclosing portion 6, when the wheel F is rotated by its handle it in the direction of the arrow, serve to positively lift the pitman-connection E; and as there are three cam-surfaces, g, and three liftingfaces, '5, which alternately come into action during a single revolution of the wheel F, the dasher B, when connected to the device E, will make three positive up and down strokes at every revolution of the wheel.

The central portion, G, at its points 8, is connected to projections s, which extend inwardly from the perimeter g of the wheel, said parts g, G, and i bein gall connected together in the operation of casting the wheel.

I The pitman-connection E, as clearly represented in Fig. 4, is adapted to work in the slot f of the standard D, and be retained therein by the overlapping portions 1. On its rear side it is provided with a friction rollerfr, which is held in place by a screw-bolt,'as shown in Fig. 2. In front it has two projecting portions, as at l 1 between which clamping or clasping jaws, as atjj, are hinged on a pin, 12. The forward ends of these jaws are perforated, and the perforation in j is screw-threaded, so as to engage the thumb set-screw m, and thereby tighten the jaws upon the dasherhandle when inserted for action between the jaws, as indicated in Fig. 2. By hinging these jaws upon the pin 19 it will be perceived that 7 they may be deflected either to the right hand,

'as indicated in Figs. 1 and 3, or to the left it will be seen that if, for any cause, the hole a in the cover of a churn through which the handle I) of the dasher works should not be in exact line with the longitudinal axis of the body A of the churn, the said mechanism for operating the dasher can be adjusted to said handle, and this without causing a binding of any of the parts during the act of churning, and also that said mechanism is adaptable to operate dashers in churns which do not have the same diameter.

It will also be seen that when it is desirable to detach the handle I) from the jaws jj a single rearward turn or two of the thumb-screw m will effect this object; whereupon, if it is desired to withdraw the dasher from the churn, the jaws may beturned to one side, as indicated in Fig. 1 in full lines, and in Fig. 3 in dotted lines, and the dasher removed, as illus trated in Fig. 1; or the standard D, carrying the pitman-connection E, may be swung around entirely out of the way of the removal of the dasher.

I claim 1. The combination of the weighted camwheel F, having a camway, w, for giving a posi- JOHN B. BOLINGER.
